Emissão de óxido nitroso e dióxido de carbono após aplicação de dejetos de suínos e bovinos em um argissolo
(Universidade Federal de Santa MariaBRAgronomiaUFSMPrograma de Pós-Graduação em Ciência do Solo, 2009-03-02)
Emission of greenhouse effect gases due to the agricultural use of the dejections of animals as fertilizers, as well as the mineralization of the carbon of those materials in the soil healthy aspects are still relatively ...
Transformações do carbono e do nitrogênio no solo e produção de aveia com o uso de dejetos de suínos em plantio direto
(Universidade Federal de Santa MariaBRAgronomiaUFSMPrograma de Pós-Graduação em Ciência do Solo, 2005-08-12)
The use of pig manure, especially of the deep-bedding manure, is not so often in the winter cover crops, preceding the summer commercial plantation. The aim of this study was to evaluate the carbon and nitrogen dynamics ...
Avaliação e modelização da dinâmica de carbono e nitrogênio em solo com o uso de dejetos de suínos
(Universidade Federal de Santa MariaBRAgronomiaUFSMPrograma de Pós-Graduação em Ciência do Solo, 2005-02-28)
The managedment of the pig manure, in the slurry or solid form (deep bedding), and how it is applied to the soil, in the surface or incorporated, must affect the dynamics of the C and the N in the soil. The objectives of ...
Biotransformações do nitrogênio no solo durante a decomposição de palha de trigo e dejetos líquidos de suínos
(Universidade Federal de Santa MariaBRAgronomiaUFSMPrograma de Pós-Graduação em Ciência do Solo, 2007-04-20)
Nitrogen is usually the element present in higher concentration in pig slurry and the one that causes the major problems related to environmental pollution, since it is subjected of several transformations after soil slurry ...
Microbiological activity and N transformations in a soil subjected to aggregate extraction amended with pig slurry
(Inst Investigaciones Agropecuarias, 2015)
Pig slurry as a fertilizer source has been extensively used in agriculture; however, in order to reduce the risks of contaminating the water supplies given its high level of N sources, it is important to understand the N ...
Copper and zinc forms in soil fertilized with pig slurry in the bean crop
(Univ Federal Campina Grande, 2016-09-01)
The application of pig slurry may have different influence on copper (Cu) and zinc (Zn) dynamics in the soil compared with mineral fertilization. The aim of this research was to determine the different forms of Cu and Zn ...
